</div><h4>Requirements:</h4>
<p>This function must not be called outside of a catch block.</p>
<h4>Returns:</h4>
<p>If the current exception object can be converted to boost::<span class="RenoLink"><a href="exception.html">exception</a></span> or std::exception, this function returns the same string value returned by <span class="RenoLink"><a href="diagnostic_information.html">diagnostic_information</a></span> for the current exception object. Otherwise, an unspecified non-empty string is returned.</p>
<p>Typical use is to call <span class="RenoLink">current_exception_diagnostic_information</span> from a top-level function to output diagnostic information about unhandled exceptions:</p>
<pre>int
main()
{
try
{
run_program();
}
catch(
error &amp; e )
{
//handle error
}
catch(
...)
{
std::cerr &lt;&lt; "Unhandled exception!" &lt;&lt; std::endl &lt;&lt;
boost::<span class="RenoLink">current_exception_diagnostic_information</span>();
}
}</pre>
